[Q] Wifi problem - Galaxy S 4 Q&A, Help & Troubleshooting

Hi,
If you can help me fix this I'll pay you.
I have rooted my i9505 using Towelroot.
The stock installed Android version was 4.4.2, the baseband version was XXUGNG8.
I have installed the philz_touch_6.58.0 recovery and tried several ROMs.
All ROMs install without problems but I can never turn on Wifi or it turns off after 10 seconds.
I have tried various kernels, modems and bootloaders.
I would like to be able to try different ROMs but prefer to have a clean 4.4.4 ROM.
If someone can help me solve the Wifi problem I'm willing to pay for it.
If you can contact me on Skype (username: marcselman) I can follow all instructions immediately.
Thanks.

Still nothing
I have now reverted back to stock ROM XXUGNG8. But even now Wifi won't turn on.
My Knox counter has been tripped but I don't care about warranty. Could it be the reason Wifi is not working though?
My offer still stands though. If anyone can add me on Skype and help me fix this I'll pay you.
Marc

The things that tip off wifi is the modem and kernel. Have you search for hlos modem

[Q] Problem with s4 wifi

I recently restored stock rom on my Samsung galaxy s4 GT-i9505 from cm11. After that, the wifi just will not turn on at all. I will get a notice when i try to turn it on. I cannot upload a screenshot of the notice i get, it says "Security notice Your device's security has blocked an action that is not permitted. No further action is required."
Please help me solve this issue if it is possible. I really hope i have not screwed up my phone :crying: Any form of help will be greatly appreciated.
Edit: I got it to work already. i guess i flashed the wrong rom on my phone. i would like to thank @samersh72 's guide and link to stock roms that helped me solve my problem
Would love to know what firmware you used, no matter what I do it does not work, have flashed multiple roms.
I removed knox and it took some of the wifi with it on I9505XXUFNB9, I can reconnect to wireless networks but the passwords wont hold. On newer roms it just doesnt work even without a rooted kernel.
Edit: Got it working too, although cf-root to thank.Phew.

Slow Internet (3G/LTE) after 4.4.2 Update

Hello Guys
Well, let me get straight to the point. After my old rom (Revolution HD3) was draining my battery pretty fast, i decided to update to 4.4.2. Well, i downloaded the latest 4.4.2 for switzerland from sammobile.com. I flashed it and it somehow was all laggy and i had fc's the whole time. After some time i was able to use the phone anyway, but it was laggy. And the problem was that my 3G connection was EXTREMELY slow. I got connection time outs the whole time and wasnt able to download anything. Well, i thought it was the rom i flashed trough odin, so i downgraded to 4.2.2, my original rom, and updated trough KIES. The rom wasnt laggy anymore, but the 3g/4g was slow. I tried different Modems and Kernels. Nothing Helped. I then decided im going back to a custom rom but the flash failed. Then i tried another rom and it failed again. So i thought it may was cause i was on 4.4.2 and tried to flash a custom rom that was 4.2.2. I then tried to reflash my stock rom trough odin, and it FAILED. And that's how i bricked my phone. I can still enter Download Mode, but can't enter the recovery anymore. What do i do? I'd like to solve both problems.
Thanks guys
Btw: I've got an I9505
I assume you didn't wipe anything before you flashed stuff? Thats like rule number 1 to do.
You can try flashing a recovery true Odin.
Hej Guys
Um.. Just to let you guys know, it is possible to downgrad to 4.2.2 from 4.4.2. I just did it this morning and had sucess. But the problem with the really slow internet connction still is here, when im on a 4.4.2. And, it is the same with custom roms running 4.4.2. I tried different kernels and modems, nothing helped so far. As soon as i was back to 4.2.2 it had the usual connection speed. I called my provider and also called samsung itself. Obviously, they both told me to bring the phone back for garantuee. But well, as i know it's a software problem and not hardware, i wont do that. So can you guys help me? What should i do next? Actually im back on 4.2.2. Thanks
Edit: Oh, and ofc, i did everything like wiping/factory resetting, wipping preoload etc. It's not my first time flashing.
It's not possible to downgrade from 4.4.2 to 4.2.2! End of..

Are you serious dude? Im running 4.2.2 right now. What is your point?`I didnt even ask about it. I asked about a solution to the problem that i get slow 3G/4G on my I9505 when running 4.4.2. If you want a proof Pic about it running 4.2.2, i can give you one. But i dont really get what your point is.
Hang on hang on hang on, it is common knowledge that you cannot downgrade from official samsung 4.4.2 to official samsung 4.2.2 because in odin you will get failure at aboot.bin because you cannot downgrade bootloader.
How ever what would be really good is instead of just trying to say it then jumping out saying what's your point, we'll my friend the point is, it would be advantageous to everyone in the entire samsung galaxy s4 i9505 community if you can tell everyone how you did it.
My perspective is your doing a bit of flaming.
Pictures really won't prove a whole lot as anyone can do some build.prop edits and show different rom name and version.

Well, if it sounded like flame to you, it wasnt. I didnt create this thread to flame others. But i wasnt kidding saying that i downgraded to 4.2.2. Here how i did it:
Was running 4.4.2 (I9505XXUFNB9)
Flashed TWRP recovery.
Flashed custom Rom 4.2.2, which FAILED!
Flashed Official 4.2.2 trough odin, which FAILED!
Flashed TWRP recovery again, since it was somehow damaged from the flash before
Flashed Wanamlite 4.4.2
Flashed Custom Rom 4.2.2
Flashed Official 4.2.2 with succes.
Im not sure what part of those flashes were essential, but i have no reason for liying to you. What would be the perks if i did?
But now again BTT, Did anyone else have that problem of slow interenet connection? Or is it just me? Maybe some ideas?
Regarding slow Internet maybe it's your carrier with issues.
Maybe the downgrade back to 4.2.2 has created issues in its self. Have you checked your baseband matches bootloader and build?
A problem we have is we can't see the version of the 4G modem (non-hols) so that might be also an issue.
When you flashed back did you do a factory reset?
In regards to downgrade do you still have the Knox bootloader?

Well, i called my operator and the girl on the phone said that some people already called with the same issue, but its not on their side. It's a problem with the update samsung released. After the downgrade i had my Knox Bootloader and everything worked like it always did.
Yesterday Sammobile released a new ''rom'' for my country. Downloaded it, flashed it and it works great now. I have a bit of a fast battery Drain, but the problem with the slow internet seems to be fixed.
Again: 4.2.2 worked perfectly after downgrade. It had no issue, No FC nothing at all. Maybe i was lucky? No idea, but im happy my 4.4.2 works now
Thanks anyway for your help guys
Edit: Yeah, my bootloader matched both baseband and build.

If you had done your homework, you would know that in almost all cases Samsung repairs it even with Knox set to 0x1. They even publicly stated it in the Netherlands that they will repair your phone even with custom roms.
And you don't know the law in Switserland. Nor do I. So you can't say that in Switserland his rights are voided by flashing.
If Samsung doesn't give you the warranty, then you still have your consumer rights in the European Union (not that Switerland is in it). No flashing, modding or other chances decleine you your rights if it's not related to a hardware failure. In the countries that you and I live in, it will never void your rights if the damage is not related to flashing or modding.
So well, i think that in switzerland they actually WONT repair it if you flash it, but i aint sure about that, since i never had to send it to repair. But anyway, it was only a software problem on their side. They released another version for switzerland and it seemed to have fixed the problem. I have a bit more of a battery drain, but i actually think im just too used to some other custom roms. Anyways, thanks for the help guys

[Q] Dialer goes black when making calls and no sound

I have an s4 from rogers (Canadian model) and initially had cyanogen mod as my rom but I realized that I was missing nearly 5 GB of storage on my phone. I read that to fix this I had to go back to stock using Odin. I went back to stock 4.2.2 using Odin, but then my WiFi stopped working. I couldn't turn WiFi on or search for networks. I then rooted my phone and installed a rom and my WiFi problem was fixed, but now I cant make calls. Every time I try to call someone my screen goes black and the recipient cannot hear me and I cannot hear them. Also, the sound on my phone does not work. I have flashed multiple roms and still get the same problem. Does anyone know any possible solution. I have looked around and many people have had the same problem, but no solution. Any help would be appreciated.
It's because you flashed an old rom (4.2.2) on a newer bootloader. That doesn't work. Flash the latest rom available for you phone.

I have flashed multiple roms and most of them were the latest ones (4.4.4). This still did not fix the problem. Is this what you mean?

I'm sorry, I gave some wrong advice.
It's probably because you are on the old bootloader but you are using a new modem. That's the cause for the problems on our s4. You have a different s4 and there is a different section for your device.
You have to be in this section:

Wifi well get stuck or well refuse to turn on if you have the wrong radio installed. You'll need a firmware and baseband that works with each other for wifi/data/cellular to work. I would reflash the Baseband

hey thanks a lot for the answer, did you midn to teach me in tutorial please
Flash a fresh firmware using ODIN or Flash a rom of your choice in recovery. It should update your baseband. Make sure its region free or made for your region. I myself have never flashed it on my Note 3. But wifi being stuck has happened to me on countless different phones and it all points the the baseband/radio installed.

WiFi issue (stuck on turning on)

Hi guys. I'm having a problem with my WiFi. It will often be stuck in trying to turn itself on and when it does switch on, it can't connect to any WiFi. I've tried rebooting my phone, flashing stock Samsung rom, re-rooting and flashing different custom roms but none of it seem to work at all. I'm currently on temasek v15.6 and using N9005.
Anyone has any idea about what may be wrong? I read somewhere online that it may be hardware issue since the radio chip houses both the WiFi and Bluetooth. I am able to use my Bluetooth without any problem so I am quite sure it isn't the radio chip problem.
What 'stock samsung rom' did you flash?
Did the bootloader and modem update?
As a last resort i'd try it with a pit file to repartition your phone.

I went to use the latest Samsung lollipop from sammobile. It changed my baseband to that version of lollipop though. What's a pit file and how is it done? BTW, I flashed to stock using odin.
This is the stock I was using. The PDA version is N9005DXUGBOF1 and the CSC version is N9005OLBGBOF1. Lollipop 5.0 (Singapore).
I've tried the method that was being recommended but still having no luck at all with my WiFi.. Thanks anyway.
